Product Lighting Layout Estimator
Use this estimator to calculate approximate fixture count, spacing, and average foot-candles for a simple rectangular space using the selected LED fixture. Enter your room dimensions, mounting height, target foot-candles, light loss factor, and room/layout condition to generate a preliminary lighting layout. When IES photometry is available, workplane height and room reflectance controls are shown.
Project Inputs
Estimated Results
Estimated average foot-candles are preliminary and should be verified with a lighting plan for project-critical applications.
Room / Layout Condition: This field is used only when usable IES photometry is not available. In fallback mode, it acts as a simplified room utilization factor for reflectance, fixture distribution, racking, obstructions, and how much fixture light reaches the work area. Open / light-colored spaces use 0.90, typical warehouses or shops use 0.75, racked or obstructed spaces use 0.60, and dark or complex spaces use 0.45. When IES photometry is active, this field is hidden and the estimator uses the selected workplane height, LLF, and simplified reflectance adjustment instead.
Photometry / Simulation Note: When usable IES photometry is available for the selected fixture, this estimator uses the fixture’s IES candela data, selected workplane height, light loss factor, and simplified reflectance adjustment to estimate fixture count, average foot-candles, and visual light distribution. The reflectance adjustment is a conservative approximation and is not a full zonal-cavity, radiosity, or professional photometric room calculation. When IES photometry is not available, the estimator uses a simulated beam model based on lumens, mounting height, room/layout condition, light loss factor, and beam angle.
Preliminary Estimate Only: This estimator is intended for simple square or rectangular spaces and should be used as a planning aid, not a final photometric lighting plan. Actual light levels may vary based on fixture optics, selected IES file, mounting conditions, workplane height, ceiling height, surface reflectance, obstructions, controls, voltage, installation conditions, and site-specific requirements. Project-critical applications should be verified with a formal lighting plan.
This estimate is a starting point. Warehouses, industrial facilities, hazardous locations, sports areas, schools, healthcare spaces, public areas, and code-sensitive projects may require a reviewed lighting layout before purchase or installation.
Product Overview
This 80-watt square explosion proof LED light delivers 11,200 lumens at 5000K for hazardous location lighting where a sealed, impact-resistant fixture is required. It is available in 100V-277V or 277V-480V configurations.
The fixture replaces 250-watt metal halide lighting while reducing connected load. Its square housing, tempered glass lens, and yoke or 3/4 inch NPT pendant mounting support fixed industrial installations.
Core Performance and Output
The fixture produces 11,200 lumens at 140 lumens per watt. A standard 120 degree beam angle provides broad distribution, with optional 40, 60, and 90 degree optics available for more controlled layouts.
It operates on 50-60Hz power with a power factor above 0.95 and THD below 10 percent. The 120 degree optic can create excessive spill or glare where fixtures are installed close to the work area, while narrower optics require layout review to maintain uniform coverage.
Adjustability and Control Options
This fixture supports 0-10V dimming. Dimming control wiring and voltage configuration should be confirmed before installation.
Available beam angles include 40, 60, 90, and 120 degrees. The optic selection affects distribution pattern and fixture placement requirements.
Longevity and Reliability
The LED system is rated for 50,000 L70 hours. The fixture includes 10kV surge protection for electrical transient protection.
Operating temperature is rated from -22 degrees F to 122 degrees F. The product carries a 5-year warranty.
Build Quality and Physical Characteristics
The housing is copper-free aluminum with a gray finish. A tempered glass lens protects the optical assembly.
The fixture is IP66 rated and IK10 rated. It measures 11.6 by 11.6 by 9.57 inches and weighs 27 pounds.
Where This Product Fits Best
This fixture is intended for classified and demanding industrial environments requiring explosion proof lighting equipment. Its Class I, Class II, and Class III ratings support use across several hazardous material and process conditions.
- hazardous location lighting
- paint booth lighting
- chemical processing facility lighting
- oil and gas facility lighting
- refinery lighting
- marine environment lighting
- wastewater treatment lighting
The IP66 enclosure, IK10 impact rating, copper-free aluminum housing, and wet-location suitability support installations exposed to dust, moisture, and physical impact.
Installation and Long-Term Use
The fixture mounts by yoke or 3/4 inch NPT pendant. The mounting structure must support the 27-pound fixture weight and maintain the required installation orientation.
Confirm the available branch voltage before installation because the fixture is offered in separate 100V-277V and 277V-480V configurations. Long-term maintenance should include inspection of the lens, mounting hardware, conduit connections, and enclosure condition.
How This Fixture Is Commonly Used
In hazardous location lighting and chemical processing facility lighting, fixtures are positioned according to mounting height, required illumination, and the selected beam angle. Pendant mounting is commonly used where the fixture needs to hang below the mounting surface, while yoke mounting allows directional aiming.
Paint booth lighting and refinery lighting layouts generally use controlled fixture placement to manage distribution across the illuminated area. Higher output can reduce fixture count, but optic selection and mounting height still determine uniformity and glare control.
